SHADE-HOLDER.

SPECIFICATION forming part'f Letters Patent No. 761,947, dated June 7, 1904.`

Application filed January 22,1904. Serial No. 190,173. (No model.)

.To all whom, t may concern: Y

Beit known that I, EARL Coornma citizen of the United States` residing at Washington, in the county of Wood and State of West ,Virginia, have invented certain new and useful Improvements in Shade-Holders; and l do declare the following to be .a full, clear, andexact description of the invention, suoli as will enable others skilled in the art yto Which it appertains to make and use the same, reference being' had to the accompanying' drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates toshade-holders for electric lights, and has for its object to provide a shade-holder which will allow the shade to be instantly attached orremoved.

lith this object in view my invention conf sists in the novel construction of the shadeholder.

My invention also consists in the novel clamping means which I employ.

My invention also consists in certain other novel .features of construction and in combination of parts, which. will first be fully described and afterward specifically pointed out in the appended claims.

Referring to the accompanying drawings, Figure 1 is a perspective view showing my shade-holder and shade inoperative position. Fig. 2 is a top plan view of the shade-holder in a clamped position. Fig. 3 is a like view of the shade-holder in an open or unclamped position'.

ltis the usual custom to construct shadeholders forelectric lights witha clampinghand and a small screw, which hand is tightened around the electric socket hy means of the small screw, which draws the two ends of the clamping-band together. It is of course evident that it requires considerable time to attach a shade-holder to the electricsocket in this manner, as it necessitates the use of a screw-driver. In order to remove-the shadeholder from the socket, it also requires considerable time, as the small screw must be unthreaded in order to release the clamping-band from the socket.

The very simple construction of my inven- -tion makes it possible to attach or detach a shade-holder from an electric socket instantly and requiring no screws, but simply utilizing a novel clamping means, which will he now described.

Referring to the accompanying drawings by reference-numerals, 1 indicates the electric socket, and 2 indicates the shade-holder, which is provided with an annular flange 3 and a series of small set-screws 4, whichy engage the shade 5 to hold the same in the shadeholder. Preferably integral with the annular flange 3 and connected thereto by the portions 6 and 7 is the clamping-band 8, having one free end 9, said hand having a normal tendency to spring open, as shown in Fig. 3. Pivoted in front of the clamping-band 8 at 10 is a lever 11, Which is provided with a projection 12, and pivoted to the free end of the clamping-band 8 at 13 is a link 14, which is also connected to the lever 11 at 15. Said link is curved inwardly at 16 to conform to the projection 12 on the lever 11 and to engage said projection, as shown in Fig. 2.

Having thus described the several parts of my invention, its operation is as follows: In

order to attach the shade-holder to the socket 1, the same is placed in position and the lever 11 is pressed into position, as shown in Fig.

2. This movement of the lever draws the free end 9 of the clamping-band 8 in contact with the socket 1, and the inwardly-curved portion 16 of the link 14 engages the side of the projection 12 of the lever 11, as shown in Fig. 2. This particular construction causes the resiliency of the free end 9 of the clamping-.band 8 to hold the lever 11 in its closed position, as

shown in Fig. 2, for the reason that as soon as the pivotal point 15 of the link 14 passes within a line taken from the pivotal point 13 of the link 14 and the pivotal point 10 of the lever 11 the spring of the free end 9 of the clamping-band 8 tends to draw the lever 11 against the clamping-hand 8, and thus hold the lever 11 in its closed position, as shown in Fig. 2. As the inwardly-bent portion 16 of the link 14 passes over and in engagement with the projection 12 of the lever 11 it effectually locks the link 14 and the lever 11 and throws the strain of the free end of the clamping-band at this point, insuring against an accidental. IOC

movement of the lever ll. 1t is therefore obvious that the stronger the tendency of the free end of the clamping-band to open the stronger and more secure is the contact of the inwardly-curved portion of the link 14 with the projection 12 of the lever ll, and consequently the stronger the tendency of the clamping-band to open the stronger and more securely is the lever 11 held in its closed position.

Having thus fully described the operation of my invention, I do not wish to be understood as limiting myself to the exact construction herein set forth, as various slight changes may be made therein which would fall Within the limit and scope of my invention, and I consider myself clearly entitled to all such changes and modifications.

That I claim as my invention, and desire to secure by Letters Patent of the United States,

1. In a shade-holder for electric lights, the combination with the socket, of a shade-holder provided with a clamping-band having one free end a lever pivoted on said shade-holder and a projection on said lever, a link pivoted to the said free end ofthe clamping-hand and also connected to the said lever, said link heing so shaped as to engage said projection ol' said lever substantially as described and for the purposes set forth.

2. A shade-holder provided with a clamping-band and a lever pivoted to said shadeholder, said clamping-band having one free end, a link pivoted to said free end and connected to said lever, and lneans on said lever for engaging said link between the two ends thereof, substantially as described.

3. A shaifle-holder provided with a clamping-band and a lever pivoted to said shadeholder, said clamping-bami having one free end, a link pivoted to said free end and connected to said lever and means on said lever for engaging said link substantially as described and for the purposes set forth.

In testimony whereof l ailix niy signature in presence of two witnesses.
